Abstract (en)
[origin: EP0320723A2] In order to achieve the most compact design possible in a power- driven machine with variable torque adjustment, having a motor and a planetary gearing driving a working spindle, comprising a rotatably mounted ring gear which actuates a motor cutoff switch counter to the action of a spring force when an adjustable limiting torque is exceeded, it is proposed, to produce the spring force, to provide a torsion-spring element which extends in the axial direction alongside the planetary gearing and which carries, at one end, a pivoting element which engages in a cam on the ring gear and, at an opposite end, is held in an abutment, that the pivoting element can pivot from a starting position counter to a force action of the torsion-spring element, and that in the process the motor cutoff switch can be actuated. <IMAGE>
